The professional identity of librarians is established with regard to the current understanding of their knowledge practices. The global phenomenon of false and untrustworthy information circulating on social media platforms paints a new issue that librarians must conquer. Messages, content, news, and information on the web make it challenging for librarians to educate users as to where the sources come from and the need to evaluate for credibility and trustworthiness. During the pandemic, and with a surge of information disorders on social media, the World Health Organization recommended building resilience to misinform-ation and engaging and empowering communities to take positive action. This research seeks to explore the relationship between professional identities and the participation of librarians in an infodiverse environment, specifically by exploring how Filipino librarians applied aspects of their knowledge practices to the evaluation of social media health information during the pandemic. 相似文献

Objective
The objective of this literature review was to summarise current research regarding how consumers seek health‐related information from social media. Primarily, we hope to reveal characteristics of existing studies investigating the health topics that consumers have discussed in social media, ascertaining the roles social media have played in consumers’ information‐seeking processes and discussing the potential benefits and concerns of accessing consumer health information in social media.Methods
The Web of Science Core Collection database was searched for existing literature on consumer health information seeking in social media. The search returned 214 articles, of which 21 met the eligibility criteria following review of full‐text documents.Conclusion
Between 2011 and 2016, twenty‐one studies published explored various topics related to consumer information seeking in social media. These ranged from online discussions on specific diseases (e.g. diabetes) to public health concerns (e.g. pesticide residues). Consumers’ information needs vary depending on the health issues of interest. Benefits of health seeking on social media, in addition to filling a need for health information, include the social and emotional support health consumers gain from peer‐to‐peer interactions. These benefits, however, are tempered by concerns of information quality and authority and lead to decreased consumer engagement. 相似文献5.

After the Spring Festival of 2015, an environmental documentary called Under the Dome in which Chai Jing acted as a narrator has caused the public opinion to boom in social media in China. Why could a documentary released by internet attract so much attention and spark such a heated discussion? What are the factors that have influence on the information dissemination of social media environmental mobilization? This paper employed case study and semi-structure interviews to reveal these questions. It turned out that individual trust, group norms and information networks of the social capital played an important role in the social media environmental mobilization. The reason why Under the Dome became a hot issue was that it made full use of the social media users’ trust on the mobilizer, aroused the mobilized’s emotions and combined the network channels of social relationships. 相似文献

Health information consumers and patients increasingly take an active role in seeking health information online and in sharing their health problems and concerns in online support groups and social media venues. However, they may risk being influenced by unreliable and misleading information in such environments, as no intermediaries monitor the quality of this information. This study focuses on evaluating the quality of health information exchanged in one of the social media venues, by investigating how librarians, nurses, and users assessed the quality of health answers in Yahoo! Answers, a social question-and-answering (Q&A) service. Through statistical analysis differences among the three participant groups, how the background characteristics influenced their assessments, and the relationships between characteristics of the content of answers and quality evaluation criteria were each considered in detail. Librarians and nurses shared similar ratings of answer quality, but had differences in their level of medical knowledge and the types of services they offer, resulting in minor differences across criteria. Users perceived the quality of health answers in social Q&A to be higher than librarians and nurses for almost all criteria. Depending on the sources of information presented in health answers, librarians, nurses, and users gave different quality assessments. Implications exist for research into and practice of evaluating the quality of health information, which need to address both search and domain expertise along with the sharing of socioemotional values preferred by users. 相似文献

Affordable and ubiquitous online communications (social media) provide the means for flows of ideas and opinions and play an increasing role for the transformation and cohesion of society – yet little is understood about how online opinions emerge, diffuse, and gain momentum. To address this problem, an opinion formation framework based on content analysis of social media and sociophysical system modeling is proposed. Based on prior research and own projects, three building blocks of online opinion tracking and simulation are described: (1) automated topic, emotion and opinion detection in real-time, (2) information flow modeling and agent-based simulation, and (3) modeling of opinion networks, including special social and psychological circumstances, such as the influence of emotions, media and leaders, changing social networks etc. Finally, three application scenarios are presented to illustrate the framework and motivate further research. 相似文献

New media literacy (NML) skills are regarded as crucial for the 21st century. However, there is limited research on the factors affecting NML skills. A robust model was built for exploring the antecedents of NML. The model incorporated epistemological beliefs and social media use purposes. Individuals` purposes of social media use were found to have an effect on beliefs about information. Further, interactional and communicational use of social media makes epistemological beliefs more sophisticated. However, it is more likely to have naïve beliefs with the use of social media for making new friends. Also, the purposes of social media use and epistemological beliefs affect NML skills. Accordingly, interactional use of social media might contribute to justifying information, in turn, increasing NML skills. This study indicates that knowledge of social media use and epistemological beliefs enables us to largely understand the NML skills. 相似文献

Knowledge sharing plays a fundamental role in the mobile social media context. However, users are more likely to believe that their knowledge sharing is not worth the effort and time given high expectation of receiving some value in return. Social media have limited value if users are not willing to share knowledge. Knowledge sharing with the consideration of transactive memory system (TMS) from the perspectives of social capital and task visibility was examined. Building on prior theories and literature, a TMS knowledge sharing research model was developed. Data were collected from users of social media mobile apps. Results show that TMS is a valid second-order construct. From the social capital perspective, cognitive capital, relational capital and structural capital each have positive effects on TMS which further has a positive effect on knowledge sharing. From the task visibility perspective, knowledge sharing visibility has a positive effect on knowledge sharing. 相似文献

This research examined the ways in which academic librarians and users interact when using social media tools such as Twitter and Weibo as well as end-users' and librarians' perceptions of the types of interaction through social media. The study conducted an analysis of 1600 microblog posts sampled from twenty university library Weibo (Chinese Twitter) sites and twenty library Twitter sites in English-speaking countries. The results were compared using Chi-Square analysis. Results indicated that at present academic librarians in English-speaking countries use post information relevant to the library (news and events) and respond to information/research inquiries. And academic librarians in China are likely to use Weibo to communicate with users and to disseminate library news. Given the lack of previous research on how social media such as micro-blogging in general facilitates communication between librarians and library users in academic libraries between in English-speaking countries and China, this study provides valuable information concerning librarians' and end-users' interactions of information/knowledge sharing activities, which will enable libraries to be better positioned to promote user engagement through SNS usage. 相似文献

In 2009, the departments in the executive branch of the U.S. federal government received the presidential marching order to “harness new technologies” in order to become more transparent, collaborative and participatory. Given this mandate, this article sets out to provide insights from qualitative interviews with social media directors to understand the factors that influence internal adoption decisions to use social media applications, such as Facebook, Twitter, or blogs. Three distinct factors influence the adoption decisions of social media directors: information about best practices in their informal network of peers, passive observations of perceived best practices in the public and private sector, and “market-driven” citizen behavior. The resulting adoption tactics include: (1) representation, (2) engagement, and (3) networking. The findings point to the need for higher degrees of formalized knowledge sharing when it comes to disruptive technology innovations such as social media use in highly bureaucratic communication environments. Recommendations based on the lessons learned are provided for practitioners and social media researchers to develop social media tactics for different organizational purposes in government. 相似文献

This study explores how audiences seek information from social and traditional media, and what factors affect media use during crises. Using the social-mediated crisis communication (SMCC) model, an examination of crisis information and sources reveals that audiences use social media during crises for insider information and checking in with family/friends and use traditional media for educational purposes. Convenience, involvement, and personal recommendations encourage social and traditional media use; information overload discourages use of both. Humor and attitudes about the purpose of social media discourage use of social media, while credibility encourages traditional media use. Practically, findings stressed the importance of third-party influence in crisis communication and the need for using both traditional and social media in crisis response. 相似文献

Public agencies need to distribute information to their manifold audience quickly and directly. The emergence of social media platforms has sparked positive projections about future government-public interactions via the internet and almost every EU agency has created social media presences on the leading social media platforms. However, social media accounts of agencies receive strongly varying amounts of public attention and therefore display varying degrees of usefulness to connect with the public. This research examines which factors influence how much long-standing and temporal attention social media accounts of EU agencies receive. Using an extensive Twitter dataset of EU agencies and a new methodology that employs supervised text classification through the novel BERT language model to classify agency tweets, possible explanations of social media attention are tested. Results show that long-standing social media attention (i.e., size of the followership) is mostly explained by salience in traditional news, account age, and tweeting frequency, whilst a more interactive communication style tends to yield more temporal attention (i.e., number of retweets). The findings underline previous assumptions that employing a more interactive communication style maximizes public organizations' potential to connect with their audiences on social media. 相似文献

Due to doubts about the reliability of information in social media environments, and the epistemological beliefs of individuals who use these media, questioning the source of information and the perception of knowledge structure, is an important research topic. A structural model was constructed to explore structures associated with epistemological beliefs (justification for knowing) and online information-seeking strategies. The model included personality traits and information literacy. Data were collected from 190 university students. PLS-SEM was implemented in the analysis of the data. Analysis revealed that there was a significant relationship between epistemological beliefs specific to social media and information-seeking strategies, and information literacy structure has a direct effect on information-seeking strategies. Agreeableness and neuroticism were related with several dimensions of social media-specific beliefs. It was found that the personality trait which has the greatest effect on online information-seeking strategies is conscientiousness. 相似文献

Objective: To explore through an interdisciplinary approach the potential to tailor health information on the basis of human information behaviour (HIB) on par with the results of basic physiological measurements of individuals’ health. Methods: The data were collected at the baseline of a physical activity and diabetes prevention intervention with 72 prediabetic participants, conducted in Oulu, Finland, by the University of Oulu and Oulu Deaconess Institute in 2010. Body mass index (BMI), fitness classifications and glucose values were obtained from all prediabetic participants. The interest in, the search for and the use of information on nutrition, physical activity and diabetes were examined through a self‐report questionnaire with a response rate of 95.8%. The data were analysed with the SPSS statistics 18 software. Results and conclusions: The study shows that information behaviour of prediabetic individuals differs according to their BMI and fitness level. Poor physical fitness classifications and high BMI values were associated with an increased desire to receive tailored information on nutrition and physical activity frequently. These results add knowledge on the types and preferred frequencies of tailored information. Because of the small sample size, the results should be validated further. 相似文献

While the use of social media by local governments has gained relevance in recent years, crises are critical situations that reinforce the need to reach citizens to disclose information, demonstrate the government's commitment, and increase the citizens' level of preparedness and awareness of resources. This paper examines the factors that influenced local governments' e-disclosure during the first wave of the COVID-19 pandemic. To accomplish this objective, we systematically tracked every post published by the official Facebook page of 304 Portuguese municipalities between March 2 and July 5, 2020. The findings show that financial autonomy is the main predictor of e-disclosure, factors varied on the different phases of the pandemic's first wave, and sociodemographic factors became more prevalent as explanatory factors when the crisis worsened. Our study may help increase the level of preparedness during possible future crises. In particular, establishing communication strategies for prolonged public health crises, making financial resources available for the accomplishment of such strategies, and reducing the digital divide can contribute to more effective disclosure. Future research should explore the dynamics of disclosure during public health crises. This study also highlights the need to incorporate time in research that focuses on the determinants of e-disclosure that could also be tested in normal times. 相似文献
